None that I know of, but those are both abandoned and all the download links for them are very sketchy.

Interesting, https://suyu.dev/ warns against doing it.

I remember there used to be images to trick t-shirt bots, in a bid to get the companies behind them sued by disney.

If bsky goes out of business and shuts down their servers, will these continue to function?

Yes, but there will be far less people since everyone’s on bsky.social. Kinda like mastodon.social.

Does bsky still have any control at all over moderation?

Great question! Bluesky has individual moderation services you can subscribe to, and these hide/label posts for you.
bsky has no control over moderation if you are not on their servers, and you are not subscribed to their moderation service.

So, bluesky works differently to fedi.

A PDS stores your posts/comments/likes/blocks/articles/whatever. These all get crawled and saved to a relay.
An appview connects to a relay and sorts through all the posts, and indexes them.
They handle all the interactions, rather than passing messages between servers.

Thats completely untrue :) .

app.wafrn.net is a separate app that connects to bluesky, atproto.africa is an alternate relay, deer.social is an alt appview.

You can use bluesky without relying on bluesky now.

Did something change since this was posted?
I can look it up properly on mastodon.
You have to be signed in to fetch accounts on mastodon, is that the problem?

Are you using any framework to build the site? There’s a few libraries for activitypub.

The ui is good, yes, but lemmy.world itself is pretty problematic.

Don’t get me wrong, if you use it, its no problem, but its not the place to direct newcomers.

I’d recommend going to lemmy.zip or lemmy.ca. They work almost exactly the same as lemm.ee, and you can interact with the same content.
